BACKGROUND OF THE INVENTION I. Field of the Invention

The present invention is related to a device for preventing curling of a rug corner.

II. Description of Related Art

Many homes, office buildings, and the like use area rugs on the floor for decorative or other purposes. These area rugs are typically rectangular in shape and ideally lie flatly on the floor surface.

Unfortunately, over time, the corners of the rug curl upwardly away from the floor surface. When this occurs, the upwardly curled corner of the rug is not only visually unattractive but also presents a safety hazard in which people can trip on the corner of the rug. This is particularly serious in commercial establishments where people who trip on the upwardly curled corner of the rug may fall and hurt themselves and create legal and financial liability.

SUMMARY OF THE PRESENT INVENTION

The present invention provides an apparatus to prevent curling of a rug corner that overcomes all of the above-mentioned disadvantages of the prior art.

In brief, the apparatus of the present invention comprises a rigid and planar V-shaped body. The body has a planar top and a planar bottom which is spaced from the planar top by a small distance, e.g one eighth of an inch.

An adhesive layer is applied to at least a portion of the top of the body. A removable protective cover is then provided over the adhesive layer to protect the adhesive layer when the apparatus of the present invention is not in use.

When use of the device of the present invention is desired, the protective cover for the adhesive layer is removed. The body is then adhered to the bottom of the rug corner by the adhesive layer. Upon doing so, the rigid and planar V-shaped body maintains the rug corner in a flat condition. Consequently, when the rug corner is again laid on the ground surface, the body is positioned between the floor and the rug corner and not only provides an anti-slip protection for the rug, but also prevents curling of the rug corner.

In another preferred embodiment, the V-shaped body is removably secured to the bottom of the rug by hook-and-pile fasteners. This allows removal of the device for machine washing of the rug.

FIG. 1 is an elevational view illustrating the application of the device of the present invention;

FIG. 2 is atop view illustrating a preferred embodiment of the present invention;

FIG. 3 is a sectional view taken along line 3-3 in FIG. 2 and enlarged for clarity, and

FIG. 4 is a view similar to FIG. 3 , but showing a modification thereof.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

With reference first to FIGS. 1 and 2 , a preferred embodiment of the apparatus 10 to prevent curling of a rug corner is shown. The apparatus 10 includes a V-shaped body 12 with a top 14 and bottom 16. The body 12, furthermore, includes two elongated legs 18 and 20 which intersect together generally perpendicularly and with a rounded nose 22.

As best shown in FIG. 3 , the body is a laminate structure and comprises a bottom elastomeric layer 24 of an elastomeric material. This elastomeric material is adapted to abut against a floor surface 26 and, in doing so, prevents slippage between the apparatus 10 and the floor surface 26.

A plastic layer 28, preferably made of polypropylene copolymer, overlies the bottom elastomeric layer 24. The plastic layer 28 is preferably made of a rigid plastic material and maintains the entire body 12 in a rigid form. The plastic layer 28 and elastomeric layer 24 are preferably approximately one eighth of an inch in thickness and are attached together in any conventional fashion. Preferably, the elastomeric layer 24 comprises a sticky gel (polyurethane gel) covered by a removable backing. Alternatively, the bottom layer comprises a synthetic rubber layer such as Santoprene® by ExxonMobil Corporation. Both layers 24 form an anti-slip layer for the rug.

Alternatively, the bottom layer 24 is made of a sticky gel. The sticky gel adheres to the floor to prevent slippage, but without marring or otherwise damaging the floor surface 26.

A thin adhesive layer 30, such as 3M adhesive (acrylic foam tape), is then provided over at least a portion of the plastic layer 28. This adhesive layer 30 is then covered by a protective cover 32, preferably made out of paper or a synthetic material, and which remains attached to the body 12 until use of the apparatus 10 is desired.

With reference now to FIG. 1 , when use of the apparatus 10 is desired, the protective cover 32, preferably made of paper, is first removed from the body 12 thus exposing the adhesive layer 30. The body 12 is then aligned with a corner 34 of a rug 36 so that one edge 42 of the one leg 18 of the body 12 extends closely adjacent one edge of the corner 34 of the rug 36 while an edge 40 of the leg 20 of the body 12 extends closely adjacent another edge of the corner 34 of the rug 36.

By pressing the apparatus 10 and leg together, the apparatus 10 is thus adhered to the corner 34 of the rug. When this happens, the rigid and planar body 12 of the apparatus 10 maintains the corner in a flat condition. As the corner is then lowered onto the floor 28, the elastomeric layer 24 contacts the floor 28 and prevents slipping of the corner of the rug. Simultaneously, the rigid body 12 maintains the corner in a flat condition.

With reference now to FIG. 4 , a modification of the invention is shown in which the plastic layer 28 and elastomeric layer 24 are detachably secured to the rug 36 by a hook-and-pile fastener 50. The hook-and-pile fastener 50, often available under the trademark Velcro®, includes a hook half 52 and pile half 54 which are respectively adhesively secured to the rug 36 and plastic layer 28, or vice versa. The hook-and-pile fastener allows the plastic layer 28 to be easily detached to permit machine washing of the rug.

From the foregoing, it can be seen that the present invention provides a simple yet effective apparatus for preventing curling of rug corners of area rugs. Having described my invention, however, many modifications thereto will become apparent to those skilled in the art to which it pertains without deviation from the spirit of the invention as defined by the scope of the appended claims.
